'RUBBER HEEL.

To all 'whom it may concern:

Be it known that I, VVILEn C. BELnNAr,

a citizen of the United ;States, residing at New York, in the countyof New York and 'State of New York, have invented certain new and -useful Improvements inRubber ljleels, of which thefollowin'g is a specification, reference being had therein tothe accompanying drawing? rubber heels to be attached to theleather The-'particular object iofthe: invention is to more eiectuallya prevnt'-fs1ipping, and

I .15 thisobject iscarried'outby constructing 'the rubber heeljwitli a centralvdepressible' portion 'whose upper surface4 forms anelevated portion adaptedAx);- be de res'sed by the leather .heel when the rnb rheel is se- -cured thereto and which depression acts m 'turn 'to depress the lowersurface somewhat below the' lower vface' offthe remainder of the rubberi'lieel. In thisiwa the connecting;of the 'rubber heel with 't e leather heel T' brings abdutthe projection downward of the wearer'comes down on the heel the:"depressi depressible portlon.

In carrying this object intoeiect I-also get the further result of a more elastic heel since this depressed portion, being protruded slightly below the general lower face o f the rubber, increases the resiliency.

It is common to recess the lower part of a rubber lie'elwith a."v iew of causing a sort of sucticnaction 'to retard slipping. But

35 that also retards the free lifting of the heel from the walking surface. My invention is the direct. reverse of this construction and is free of this retarding effect on the lifting of the heel. 1 "Pf 40 -In the accompanying drawings forming a part of the specification, Figure 1 is a per spective view of the Vlower' face of my im.-

proved rubber heel; Fig. 2 is a like view of the upper surface of such heel; and Fig. 3

is a vertical sectional view of the rubber heel and the leather heel of a shoe, showing the two heels attached together.

The numeral l designates my improved rubber heel generally, it'being made of the .usual or any approved rubber 4compounds to give the requisite strength and the desired resiliency. It has a series of openings -2 through which the fastening devices, as

braids, are extended when driven into the l leather heel of the shoe. These are ordinary Application led September 16, 1918. Serial No. 254,201 l This invention relates to improvements i.

features. In the bodyor'. the rubber-heel, preferably substantially central, 'I form a portion which I will designate-asa depressible gripping section 3. This section is fashioned' on 4its upperface, preferablyninco the form of acone so that the apexor point Contact will slightly depressthqesction 3.

Accordingly, by iny improved :rubber heel I have attained the important primary result of increased gripping-of the hel to the pavement or walking surface in atnian- A -weight of the wearer.
